8.7/2=q/4
multiply both sides by 4: q=8.7/2*4
multiply both sides by 2: 2q=8.7 times 4
refine the equation: 2q=34.8
multiply both sides by 10: 20q=348
Divide both sides by 20: 20q/20=348/20
refine the equation for the final answer: q=87/5
Answer:
y is 1/4 when x is -1 if I did interpret your equation right. Please see that I did.
I believe the equation to be
. If you meant
, please let me know.
Thanks kindly.
Step-by-step explanation:
If (-1,y) lies on the graph of
, then by substitution we have:
.
We just need to simplify to determine y:
Multiply the 2 and -1:

Use reciprocal rule for exponents to get rid of the negative:

just means
:

.
There are 5 letters in the word "prime"
Imagine we had 5 slots to fill. They are empty initially.
Slot 1 has 5 choices to pick from
Once we pick a letter, we have 4 choices left over for slot 2
Slot 3 will have 3 choices
Slot 4 will have 2 choices
Slot 5 will have 1 choice
We have this countdown: 5,4,3,2,1
which multiplies out to 5*4*3*2*1 = 120
There are 120 unique ways to arrange the letters. Order matters. Because order matters, this is a permutation.
The value of y will be equal to 4.
Reason : The length of the opposite cord is equal and therefore the distance from the centre to the cord will be equal.
Ans: 3rd option (4)
Hope this helps!

When we talk about the function
